ABSTRACT

An in-ground geothermal heat pump (GHP) closed loop design program is disclosed for designing, analyzing, and simulating a detailed model and analysis of a proposed buildings in-ground geothermal heat pump system, including borehole length, number of boreholes, heat pump capacity, grid layout, total electric operating costs, efficiency ratios, and hybrid designs, among others. In one aspect of the disclosure described herein, the GHP design program can reliably and efficiently predict the fluctuations of the GHP equipment performance in very small increments which enables the determination of energy consumption and demand information on a specific and unique hourly schedule basis for a proposed building design, including incorporating thermal load data for each individual zone of the building. More specifically, the small increment method here can be used to eliminate overly broad approximations by evaluating GHP performance that is specific to building dynamics, constants, and variables for all of the building individual zones and the building&#39;s hourly operating schedule, thereby providing an efficient, reliable, simple, and effective geothermal heat pump design and simulation model.

CROSS-REFERENCE TO RELATED APPLICATION

This application claims the benefit of U.S. Provisional Application No. 61/971,716 filed on Mar. 28, 2014, which is incorporated herein by reference in its entirety.

BACKGROUND

This section is intended to introduce the reader to aspects of art that may be related to various aspects of the present disclosure described herein, which are described and/or claimed below. This discussion is believed to be helpful in providing the reader with background information to facilitate a better understanding of the various aspects of the present disclosure described herein. Accordingly, it should be understood that these statements are to be read in this light, and not as admissions of prior art.

A geothermal heat pump or ground source heat pump (GHP) is a central heating and/or cooling system that transfers heat to or from the ground. The traditional heat and cooling equipment delivered from the manufacture uses air for cooling and heating operations. GHP systems can use the earth as a heat source in cold winter climates or as a heat sink in warm summer climates. This design takes advantage of the moderate temperatures in the ground to boost efficiency and reduce the operational costs of heating and cooling systems, and may be combined with HVAC systems and energy conservation systems. GHPs employ a heat exchanger in contact with the ground or groundwater to extract or dissipate heat. This component accounts for anywhere from a fifth to half of the total system cost, and would be the most cumbersome part to repair or replace. In conventional GHP systems, the heat exchanger unit is in fluid communication with a loop of tubing buried in the ground, commonly referred to as a ground loop. A variety of ground loop configurations can be used with geothermal heat pump systems. For “closed-loop” configurations, in which the ground loop provides a closed circuit for the circulating heat exchange fluid, two known configurations are commonly employed, namely horizontal closed-loop and vertical closed-loop configurations. In the horizontal closed-loop configuration, the ground loop is typically laid horizontally, or in a directionally drilled borehole, in a shallow trench dug into the ground adjacent to a building structure that is to be serviced by the geothermal heat pump system. In the vertical closed-loop configuration, the ground loop is typically placed in a 100 foot to 400 foot deep borehole formed in the ground adjacent to the building structure to be serviced by the GHP system. The heat exchanger unit must specifically be designed for the specific location and application. Correctly sizing the heat exchanger and loop configuration and design is necessary to assure long-term performance and energy efficiency of the whole system.

Even though geothermal heat pump equipment is know to be very energy efficient, sales in the United State have been limited to generally about 1.5% of the heating and cooling industry. One of the main causes for limited sales is the lack of knowledgeable people in the industry that know how to accurately design the in-ground heat exchanger required. Designing geothermal heat pump equipment for residential, commercial, and institutional buildings can be very complex especially for models that have a very high level of detail. GHP designers can easily be overwhelmed with the amount of information and variables for designing such GHP systems without the help of computer based design analysis and simulations.

Currently, there are many types of software programs that exist for in-ground vertical or horizontal loop geothermal heat pump design and simulation. However, these programs are largely ineffective, typically designed for residential applications (not commercial), provide a complex user interface, have limited or no internet/web based accessibility or connectivity, have slow computational speeds, require other third party front-end software for various calculations, and do not have up to date or real time data of geographical, weather, climate, soil, rock data, do not allow detailed parameters and multiple zones of a building design to be set (i.e. schedule/time for multiple building zones), do not allow for hybrid designs and comparisons (i.e. adding/removing cooling towers), do not provide accurate results that allow a designer to be confident in implementing the data in a real-world application, and the programs themselves are costly to develop, operate, distribute, and be adopted by commercial designers.

Hence, what is needed is a simple to use web-based geothermal heat pump design, simulation, and analysis program that can be accessed by users using any type of mobile or computing device, provides a simple to use interface, allows the user to run multiple design and analysis simulations, select from multiple heat pump manufacturers, automatically populate and gather geographical, building, and hourly weather data in real-time, allow the user to set exact and specific building parameters (such as a buildings schedule/operational hours for each zone within a building), automatically correct raw heat pump data into actual heat pump performance, and further provide actual cost basis, hybrid designs, operating costs, benchmark, and efficiency comparisons.

BRIEF SUMMARY

In one aspect of the disclosure described herein, an in-ground GHP design program (referred to hereinafter as “GHP application” or “GHP program”) is provided for designing, analyzing, and simulating a model of a detailed building energy analysis, using an in-ground geothermal heat pump system. In one aspect of the disclosure described herein, the GHP design program can reliably and efficiently predict the fluctuations of the GHP equipment performance in small increments. This enables the determination of energy consumption and demand information on a specific and unique hourly schedule basis. More specifically, the small increment method here can be used to eliminate overly broad approximations by evaluating GHP performance that is specific to building dynamics, constants, and variables for all of the building individual zones and the building's hourly operating schedule.

In addition to building energy analysis and geothermal design applications, the small increment method of the disclosure described herein can be used for hybrid GHP systems, such as in combination with cooling towers. More specifically, in scenarios where cooling loads are very dominant, supplemental heat rejecters such as cooling towers can be used. Further, various operating strategies and conditions can be utilized in hybrid systems with the GHP design program of the disclosure described herein. For example, in order to reduce heat build-up in the ground, the GHP system can be simulated, modeled, and programmed to run during the winter, or consider running at night during the summer. In order to quantify the impact of various operating strategies on the in-ground heat exchanger size and operating costs, it is advantageous to utilize the GHP program of disclosure described herein for a GHP design model is advantageous since it can account for the hourly operating schedule and interaction between the in-ground heat exchanger and heat rejecter. For example, by modeling and simulating the use of supplemental heat rejecters (i.e. cooling towers) for cooling in building systems allows for a GHP design having smaller borehole fields, and thus reducing overall installation and operating costs, both in the near term and long term. Here, earth thermal degradation can be avoided by offsetting the annual load imbalance in the borehole field and the resulting long-term temperature rise.

Here, the standardizing can be based on one or more iterations of the performance data. The method can also include determining the capacity of the heat pump based on the standardized heat pump performance data, and also simulating or modeling a benchmark comparison of another geothermal heat pump system having different heat pump data. The method can also include receiving internal heat gain data for the building, wherein the heat gain data can include heat generated from one or more of: lighting, persons, occupancy, appliances, electronics, heat dissipating devices, windows, and building type.

FIG. 1 illustrates a general overview of a flowchart for one embodiment of the GHP application. For example, at step 2000, a user can visit a portal for the GHP application and be prompted to login or register with the GHP application network. If the user is not yet a registered user, then they can create a user profile having a username and password. Once registered, the user can enter their username and password for authentication with the GHP application. If authentication is successful at step 2020, then the process can proceed to step 2040. At step 2040, the user can select one or more geographical or location data for a building design site. Here, the location data can be retrieved from anywhere in the world, or any map data available on Google® or online mapping or geographical service and the data can be retrieved from, read from, saved to, or written to database 2042. Here, this geographical or location data can include weather data, temperature data, temperature profile data, climate data, environmental data, soil data, borehole data, ground condition, earth related data, and statistical data, among others. It is contemplated within the scope of the disclosure described herein that the GHP application can retrieve this from a database which can be residing locally on a server or retrieve this data from third party source either in real-time or previously downloaded at another time. Once geographical data from step 2040 has been received, then the process can proceed to step 2060. At step 2060, the user can be prompted to either manually input or select one or more types of buildings that the user will be designing. For example, these can include commercial, residential, house, office, retail, school, warehouse, high-rise, mid-rise, condominium, single family home, townhome, building capacity, building dimensions, building size, among others. The user also has the option to go back to step 2040 to make any changes. Once a building type data is received, then the process can then proceed to step 2080.

At step 2080, the user can be prompted to manually input or select operating schedule data for the building, which can be retrieved from, read from, written to, or saved to database 2082. For example, the operating schedule data can include but is not limited to operating months/days/hours/minutes, open business months/days/hours/minutes, closed months/days/hours/minutes, peak or off peak months/days/hours/minutes. In addition, the schedule data can be provided in database of the GHP application or retrieved via network from one or more remote sources. Once the operating schedule data is received by the GHP application, the process can then proceed to step 2100. At anytime, the user also has the option to go back to step 2080. At step 2100, the user can manually input or select design temperature and flow rate data (GPM/ton) for the building design which can be retrieved from, read from, saved to, or written to database 2102. Alternatively, the design temperature and/or flow rate data can be automatically pre-populated by the GHP application based on the prior received location and climate data. The building design temperature and flow rate data can include but is not limited to: design entering water and air temperatures for heating and cooling, thermostat inside of building for heating and cooling, flow rate (GPM/ton), type/quantity of antifreeze additive, and circulating water freeze point, among others. Once the building design temperature and flow rate data is received, the process can proceed to step 2120. At anytime, the user also has the option to go back to step 2100.

In addition, prior to proceeding to step 2120, the process can automatically detect or ask the user if this is the first time they are inputting the design parameters of step 2100. If this is the first time, then the process can proceed to step 2120, if not, then the process can automatically direct the user to step 216. Alternatively, the user can manually move to step 2160 or proceed to step 2120. At step 2120, the user can select or manually input borehole and grout data for the building design, including but not limited to: borehole diameter, HDPE pipe diameter, HDPE resin, SDR ratio, ground conductivity, and configurations for u-tube piping in the boreholes, among others. Once the borehole and grout data is received by the GHP application, then the process can then proceed to step 2140. At step 2140, the user can manually input or select ground conditions, such as ground thermal resistance data. The ground conditions can include but is not limited to: ground conductivity, ground diffusivity, thermal resistance, undisturbed earth temperature, ground density, ground moisture, long term ground effect forecast years, distance between boreholes, and loopfield grid layout, among others. Once the ground conditions or ground thermal resistance data is received at step 2140, then the process can process all prior inputted/selected and received data in combination with the borehole resistance data at step 2152 and ground resistance data at step 2154 and direct the user to the building zone module at step 2160, wherein the user can select or input data for individual zones 2180. Alternatively, the user may manually select to go to building zone module step 2160.

At step 2160, the user can be presented with a building zone module hub, page, or portal, wherein one or more of the aforementioned user selected data and/or calculated and computer data can also be presented to the user for review, selection, or input. Further the building zone module 2160 allows the user to enter, select, and input a variety of attributes related to a zone within the building. Here, zones can be a floor, room, open space, closed space, or any area in or around the building. For example, the building zone module data can include, but is not limited to: individual zone display loads, type of zone area (i.e. general office, conference, utility room, etc.), square footage of the zone, heat pump type/number, zone capacity, and electric operating costs, among others. Further, there can be any number of independent zones, such as from 1-1,000 zones. If this is the first time that the user is inputting data for a particular zone, then they can automatically be directed to step 2170.

At step 2170, the user may input or select the internal heat gain data or accept the estimated heat gain data generated by the GHP application. Heat gain data can include but is not limited to: heat gain parameters such heat generated from light, people, number and type of appliances, electronics, and heat dissipating devices in use, percentage of area comprised of windows/glass, type of building and use, lighting wattage/square footage, square footage occupied per person, and BTUs per person, among others. Once the internal heat gain data is received at step 2170, then the process will go step 2180, via module 2160.

At step 2180, which can be performed within the building zone module portal 2160, the user can optionally revise prior input (such as prior heat gain parameters from step 2170) or enter new input for the zones in addition to inputting or selecting various other parameters, including but not limited to type of zone, square footage of the zone, heat pump type, make, or model, a hybrid design percentage, the building zone's current or anticipated peak/block cooling and heating loads, and the building zone's internal heat gain parameters such heat generated from light, people, number and type of appliances, electronics, and heat dissipating devices in use, percentage of area comprised of windows/glass, type of building and use, lighting wattage/square footage, square footage occupied per person, and BTUs per person, among others. Once the parameters are selected or inputted, then the process can proceed back to step 2160.

More specifically, at step 2182, which can also be within the building zone module portal, the user can input and select one or more types of heat pumps for the selected zone, and the GHP application can later determine and simulate the quantity of the selected heat pumps are required for the GHP design and at what operating capacity they are to run, such as part, full, or variable capacity. The heat pump types can be include the brand, model, and series, wherein the model or series can indicate the heat pump's capacity/tonnage, among others, and wherein the brands can be from a variety of manufacturers including but not limited to Carrier®, Bosch®, ClimateMaster®, DaikinApplied®, FHP_mfg, GeoComfort®, GeoExcel®, HydronModule®, Tetco®, WaterFurnace®, among others. Further, the technical specifications and performance data for each heat pump type, model, and series can be saved and retrieved from one or more tables within database 2176. Further, the heat pump technical and performance data within database 2176 can be also be automatically updated when new heat pump types and/or performance data is available. The heat pump performance data can include but is not limited to size, power, capacity, flow rate, airflow data, entering water temperatures, air temperatures, anti-freeze type, and freeze points, among others. More specifically, the heat pump performance data can include minimum and suggested/recommended loop flow rate for capacity (BTU/hr) and power (kW) over a range or increments of entering water temperatures for cooling (i.e. 60, 70, 80, 90, and 100 deg. F.) and heating (i.e. 30, 40, 50, and 60 deg. F.) for heating. Further, the aforementioned published heat performance data is later standardized and corrected by the GHP application for motor type, airflow, air temperature, anti-freeze type, and freeze points based on the GHP design parameters for the building's zone, which will be described in more detailed in the disclosure described herein.

Still referring to step 2182, the user is prompted or required to input or select a maximum or peak/block BTU heating and cooling loads for the selected zone, more specifically, the maximum or peak load conditions for the heat pump(s). In addition, the user can input or select an internal average heat gain. Alternatively, the GHP application can provide an estimated heat gain value for the individual selected zone that is based on prior received data about the building, zone, and GHP design. Further, it is noted that the internal heat gain values should be entered independently of the heating and cooling loads. The entered and received maximum heating, cooling, and internal heat gain parameters are then written and saved to database 2172, where they will be retrieved by the GHP application for further processing.

Referring back to step 2180, the previously received zone data can be stored to and/or retrieved from tables within database 2172, wherein step 2180 can also store data to and/or retrieve data from database 2176 and further send this data to step 2174 and 2178 for processing (or back to zone module 2160), wherein the processed data of steps 2174 and 2178 can be transmitted back to the building zone module at step 2160, thereby providing updated GHP design data for the selected zone. Regarding hybrid design, the user has the option of running a hybrid GHP design simulation. If the hybrid design simulation selected from the building zone module, such as 1%-99% of the GHP system design being hybrid, then the GHP application can calculate and simulate a hybrid design at step 2220 and present the hybrid design data model and simulation at step 2240. Alternatively, if no hybrid design is selected (0% hybrid) then the process can calculate and simulate benchmark parameter design parameters entered at step 2250 and model at step 2200 and present this data to the simulation and model step 2240. Here, it is contemplated within the scope of the disclosure described herein that the hybrid design can be for heating or cooling. For example, for hybrid cooling, one or more of a cooling tower, fluid cooler, condenser, or chiller, alone or in combination, may be incorporated into the GHP simulation. For hybrid heating, a boiler, furnace, hot water heater, or secondary ground loop, alone or in combination, may be incorporated into the GHP simulation. Here, the one or more hybrid heating or cooling apparatuses can be activated at a pre-defined operating schedule or pre-set temperature threshold, when a maximum heat pump load is reached, or when an entering water temperature threshold is reached, or combination of the one or more aforementioned conditions. Here, the hybrid apparatuses can work in combination, and/or simultaneously, with the GHP heat pumps and system, thereby handling a percentage of the overage load/capacity that has exceeded the threshold maximum load/capacity for the ground loop.

Regarding step 2250, the user can optionally select or manually input benchmark or comparison data at step 2250, including but not limited to benchmark inputting or selecting entering water temp for cooling and heating, a cost for ground loop or borehole installation, and utility electric rate, among others. Once the benchmark data is received at step 2250, then process can proceed to step 2200 and subsequently step 2240 for simulating and modeling the GHP system with the benchmark data. Alternatively, if the user selects the previously aforementioned hybrid design (step 2220), then the user can select or input various hybrid design parameters including but not limited to the type of hybrid apparatus (i.e. cooling tower, fluid cooler, chiller, boiler, furnace, water heater, etc.) including its brand and model, hybrid entering water temperature, condenser type, fan size, fan efficiency, pump size, and pump efficiency, among others. Once the hybrid design data is received, the process can then proceed to step 2240 for modeling and simulating the GHP system having a hybrid design, such as a GHP system in combination with one or more cooling or heating systems, as previously described.

At simulation and modeling step 2240, the user can be presented with one or more portals, user interfaces, or screens for illustrating one or more models and simulations based on the computations and/or calculations performed using the one or more user selected data in one or more of steps 2040-2220. For example, the simulation data can include but is not limited to borehole length, borehole length for a 5-25 year period, number of boreholes, length per borehole, long term ground effect, borehole length for a 1 year period, design heat pump inlet, design heat pump outlet, all zones building Btu load, total heat pump capacity, hybrid design data, all zones peak demand, all zones flow rate, annual EER/COP, electric operating costs, benchmark heat pump inlet, excess length, excess length payout, undisturbed earth temperature, ground conductivity, ground diffusivity, pipe diameter, borehole diameter, grout conductivity, borehole resistance, ground moisture, building operational schedule/hours, distance between boreholes, grid across field, and grid down, among others. In addition, once at step 2240, the user further has the option to go back to any one or more of steps 2040, 2060, 2080, 2100, 2120, 2140, 2160, 2170, 2180, 2182, 2200, 2200, and 2250, among others, in order to modify, add, or remove selections or data, thus instantly, simultaneously, or in real-time modifying and updating the design simulation at step 224. For example, in one embodiment, all of the portals or screen for steps 2040, 2060, 2080, 2100, 2120, 2140, 2160, 2170, 2180, 2182, 2200, 2200, 2250, and 2240 can be presented to the user on one display screen, tab, page, web page, or user interface wherein the user can move, scroll, or swipe up, down, left, or right in order to simply switch from one portal or screen to another, thus allowing the user to run several simulations without much effort in a simple and easy use user interface.

FIG. 2 illustrates a more detailed flow chart diagram of the embodiment of FIG. 1, further illustrating the transmitting to and/or reading of data from databases 2042, 2062, 2082, and 2102 to and from zone summary portal 2160. In addition, FIG. 2 also further illustrates the transmitting to and/or reading of user selected data from data selection input portals 2062, 2084, and 2104 to and from building zone module portal 2160 for each zone within the building.

FIG. 3 illustrates a more detailed flow chart diagram of FIG. 1, further illustrating the process for processing and calculating borehole resistance at step 2152. More specifically, once borehole grout and ground condition data is received at steps 2120 and 2140, the process of the GHP application can extract data from a plurality of array tables, such as Tables 7, 8, 9 (which receive data from table 6), and received from steps 2120 and 2140. Here, at step 2152, for the borehole resistance data, the process will begin by extracting elements and values for the pipe, resin, u-tube geometry coefficients. Next, the process can set inside pipe diameter data variable (Inside Diameter=outside diameter−(min wall*2)), and a configuration factor variable (Configuration Factor=geometry1 coeff*power((bore dia/outside dia), geometry2 coeff)). Next, the pipe resistance data using high-density polyethylene (HDPE) for a single u-tube (U-Tube=(1/(2*3.14159*0.40))*(log (outside dia/inside dia))/2) and double-u tube configurations (Double U-Tube=(1/(2*3.14159*0.40))*(log (outside dia/inside dia))/4) will be set with graphite data or without graphite additive. Next, the process will set the grout resistance variable (Grout Resistance=1/(Configuration Factor*Grout Conductivity)). Finally, the process can then add the calculated pipe resistance and grout resistance data in order to set a borehole resistance variable (Borehole Resistance=Pipe Resistance+Grout Resistance). The calculated borehole resistance variable and data can be then be sent to the building zone module 2160.

FIG. 4 illustrates a more detailed flow chart diagram of FIG. 1, further illustrating the process for processing and calculating ground resistance at step 2154. More specifically, once borehole grout and ground condition data is received at steps 2120 and 2140, the process of the GHP application can extract data from one or more array tables, such as Tables 10 and 11, and received data from steps 2120 and 2140. More specifically, the process will calculate ground resistance elements or variables years, months, and ¼ of a day for three separate solutions for the temporal variations in heat flux by superposition of incremental integral expressions for when each interval of the time elements began or ended. First, a dimensionless value or number can be calculated related to time, bore diameter, and ground thermal diffusivity; (Zyears=(4*ground diffusivity*3680.25)/power (bore dia, 2); Zmonth=(4*ground diffusivity*30.25)/power (bore dia, 2)); Z.25 day=(4*ground diffusivity*0.25)/power (bore dia, 2)). Next, G-cylindrical value for each increment at first step is calculated and set; (Lyears=Log 10(Zyears); L month=Log 10(Zmonth); L.25 day=Log 10(Z.25 day)). Next, a Gvalue for each increment is calculated and set at a second step; (Nyears=−0.89129+((0.3608*Lyears)−(0.05508*(Lyears*Lyears))+(3.5917*(power(10,−3)*(Lyears*Lyears*Lyears)))); Nmonth=−0.89129+((0.3608*Lmonth)−(0.05508*(Lmonth*Lmonth))+(3.5917*(power(10,−3)*(Lmonth*Lmonth*Lmonth)))); N.25 day=−0.89129+((0.3608*L.25 day)−(0.05508*(L.25 day*L.25 day))+(3.5917*(power(10,−3)*(L.25 day*L.25 day*L.25 day))))). Then, a G value for each increment is calculated and set at a third step is set; (Gyears=power(10,Nyears) Gmonth=power(10,Nmonth) G.25 day=power(10,N.25 day)). Finally, ground resistance value are calculated and set for the prior calculated data and elements; (Ra=(Gyears−Gmonth)/ground conductivity; Rm=(Gmonth−G.25 day)/ground conductivity; Rd=G.25 day/ground conductivity). The processed and calculated ground resistance values are then sent to the building zone module 2160.

FIG. 5 illustrates a more detailed flow chart diagram of FIG. 1, further illustrating the process for inputting the maximum peak/block building cooling and heating loads for each zone at step 2180. More specifically, step 2180, which can be performed within the building zone module 2160, can receive the internal heat gain data and heat pump equipment data. Here, the process can determine if the received heat pump equipment data is a single, dual, or variable capacity heat pump and standardizing/iterating the manufacturer published performance data for the various capacity heat pumps based on cooling and heating inlet temperatures and flow rate. Here, if the heat pump is a single or dual capacity, then the heat pump performance data within database 2176, and more specifically database 2176A for full capacity operation will be retrieved. The performance data will then be processed for the received maximum peak/block heat pump load for that particular zone.

Still referring to FIG. 5, the description for the processing and heat pump performance data and standardizing flow rate for GPM/ton for single or dual capacity or stage heat pump at full capacity can include the following process: Applying GPM/ton from a table array of data and extract the adjacent elements for Cooling & Heating design temperature and flow rate; then interpolating the elements for capacity and power (kW) and correcting the manufacturer published capacity and power (kW) data for air flow, air temperature, antifreeze in circulating water; and finding the number of heat pumps that meet the loads. Here, Tables 13, 14, 15, 16, and 17 show sample data, elements, and units for the heat pump data retrieved from a database, such as database 2176, for the aforementioned heat pump performance, correction, and standardization process. Once the standardized or corrected single or dual capacity heat pump at full capacity data is processed for the maximum load, then it can be sent back to the building zone module 2160.

Still referring to FIG. 5, if a variable capacity heat pump data is received, then the heat pump performance data for full capacity will be retrieved from database 2176A and calculated similar to how it was performed for the dual or single capacity heat pump (as described previously) to obtain a variable maximum capacity data. In addition, the heat pump performance data for nominal capacity will be retrieved from database 21768 and calculated to obtain a variable nominal capacity data, and more specifically, an embodiment for the obtaining the variable nominal capacity data in one embodiment can include the following process: Applying GPM/ton from a table array of data and extract the adjacent elements for Cooling & Heating design temperature and flow rate; then interpolating the elements for capacity and power (kW) and correcting the manufacturer published capacity and power (kW) data for air flow, air temperature, antifreeze in circulating water.

Still referring to FIG. 5, once the variable maximum and variable nominal data is calculated, these data sets will then be interpolated/iterated to obtain another set of data that includes corrected and standardized heat pump performance data, such as capacity and power. Here, Tables 13, 14, 15, 16, and 17 show sample data, elements, and units for the heat pump data retrieved from a database, such as database 2176, for the aforementioned heat pump performance, correction, and standardization process. Here, once the variable capacity is interpolated for the variable full capacity (maximum) and nominal capacity (nominal) for the maximum load, then the standardized data can be sent back to the building summary module 2160. For a more detailed process flow chart for processing the heat pump performance data for the maximum load and standardize the flow rate for GPM/ton we can refer to FIGS. 5A and 5B, wherein FIGS. 5A and 5B will later be described in detail in the disclosure described herein.

Here, in one embodiment, the GHP application process must perform the heat pump performance correction and standardization processes for a maximum peak/block heat pump load for the particular zone first before running the same process again (performing the heat pump performance, correction, and standardization) according to the hourly building operating schedule data in order to obtain the most accurate data, which will be described later in the disclosure described herein. However, it is contemplated within the scope of the disclosure described herein that heat pump performance correction and standardization processes can also be incorporated in lieu of or in combination with the aforementioned processes.

FIG. 6 illustrates a more detailed flow chart diagram of FIG. 1, further illustrating the process for calculating heat pump capacity and demand data at step 2178, and more specifically an iteration process for calculating, normalizing, standardizing, or correcting the heat pump performance data in each step for the building zone thermal loads based on the hourly building operating schedule data. The process flow illustrated in FIG. 6 follows a similar methodology as illustrated in FIGS. 5, 5A, and 5B, with the exception of the processing of the heat pump data for each iteration step for the hourly building operating schedule data and additional processing for variable capacity heat pumps. In addition, FIG. 6A illustrates a more detailed flow chart process for the embodiment illustrated in FIG. 6, wherein FIG. 6A will later be described in detail in the disclosure described herein.

Referring to FIG. 6, once the heat pump data has been processed, standardized, and corrected using the maximum load data (FIGS. 5, 5A, 5B), then at FIG. 6 the GHP application process will again determine which heat pump capacity was selected by the user, or received by the GHP application, and whether the received heat pump data is a single, dual, or variable speed. The process will retrieve corresponding heat pump data from database 2176. More specifically, if a single capacity heat pump is selected, then full capacity data will only be retrieved from database 2176, and the process proceed to step 2178, wherein the heat pump performance data is processed, corrected, and standardized for full capacity at each step for each hourly building operating schedule data for an individual zone. If a dual speed or dual capacity heat pump is selected, then full capacity and part capacity data are retrieved from database 2176 and the process proceeds to step 2178, wherein the heat pump performance data is processed, corrected, and standardized for part capacity at each step for each hourly building operating schedule data for an individual zone. More specifically, each iteration step is calculated and for each iteration step load (i.e. the zone BTU/hr) if the calculated step load value is less than the part capacity value, then the process will send the calculated step load value to the building zone module 2160 for the heat pump operating at part capacity. If the calculated step load value is greater than the party capacity, then the calculated step load value is sent to the building zone module 2160 for the heat pump operating and full capacity.

Still referring to FIG. 6, if a variable capacity heat pump is selected, then full capacity, nominal capacity, and minimum capacity data is retrieved from database 2176, and the process will then proceed to step 2178, wherein the full capacity, nominal capacity, and minimum capacity data is iterated, interpolated, and standardized. More specifically, the process can first interpolate/iterate the full and nominal heat pump capacity and power (kW) data. The process can then determine if the calculated step load value is greater than the nominal capacity value and send the heat pump data for full and nominal capacity to building zone module 2160 for each calculated step data for each hourly building operating schedule for the heat pump operating at full and nominal capacity. Further, the process can interpolate and iterate the nominal and minimum heat pump capacity and power (kW) data. The process can then determine if the calculated step load value is less than the interpolated nominal and minimum capacity value and send the heat pump data for nominal minimum capacity to building zone module 2160 for each calculated iteration step data for each hourly building operating schedule for the heat pump operating at nominal and minimum conditions.

FIG. 7 illustrates a more detailed flow chart diagram of FIG. 1, further illustrating the process for calculating the zone monthly operating rate and processing the building hourly operating schedule. More specifically, the GHP application will process the building hourly operating schedule for each zone and set iteration steps by transposing the received hourly climate data by each degree of ambient temperature, wherein the process will iterate each step by each degree of temperature. Here, the process will start by applying internal heat gain for each building zone thermal loads (Beginning Step Temp=design air temp−(zone internal gain/((zone bldg loads−zone internal gain)/(design max temp−design inside temp))). Next, the process can process/calculate either or both the heating and cooling monthly BTU operating rate by applying the building hour operating schedule data for the hottest/warmest month (for cooling design/mode) and the coldest month (for heating design/mode) in steps for each zone of the building, or building zone thermal load, which in one embodiment for a cooling design can include: Step Zone Btu/hr=zone design loads btu/hr/(design max temp−beginning step temp)*(step temp−beginning step temp); Step Btu Load=each step operating month hours*step zone btu/hr; Month Btu Load=summarize the step btu loads; Zone Cooling Monthly Operating Rate (%)=month btu load/(zone design loads btu/hr*744).

Still referring to FIG. 7, the process can then proceed to balance each zone ground heat exchanger length and reset the entering water temperature if required. In one embodiment for a cooling design, the calculation can include: Zone Heat Rate=((zone loads+(3.412*heat pump power))*borehole resistance+(monthly operating rate*monthly ground resistance)+0.25 day ground resistance); Cooling Length Heat Exch.=(zone heat rate/((entering water temp+2.2)−undisturbed earth temp) heating length; Zone Heat Rate=((zone loads−(3.412*heat pump power))*(borehole resistance+(monthly operating rate*monthly ground resistance)+0.25 day ground resistance); Heating Length Heat Exch.=(zone heat rate/(undisturbed earth temp−(entering water temp−3.5)); Shortest Cooling or Heating Length=zone cooling length−heating length; Reset Heating Entering Water Temp=undisturbed earth temp−(zone heat rate/heating length). The process continues on FIG. 8 further illustrating the process for calculating the zone monthly operating rate and processing the building hourly operating schedule, and BTUs transferred to and from the ground.

Referring now to FIG. 8, for each iteration step temperature in the ambient range beginning with the highest temperature, the process applies the hours of the operating schedule data at each step temperature. Next, the process will calculate the zone (BTU/hr) for each step, wherein in one embodiment for a cooling design can include: Step Zone Btu/hr=Design zone btu/hr/(design max temp−beginning step temp)*(step temp−beginning step temp). Next the process will calculate the entering water temperature for each step, wherein in one embodiment for a cooling design can include: Step Entering Water Temp=design entering water temp−((design max temp−step temp)/design max temp−design inside temp)*(design entering water temp−undisturbed earth temp)); or an alternate method−general form including Step Entering Water Temp=((step zone btu/hr*((borehole+ground resistance)+monthly operating rate*ground resistance)*g-function)/length)+undisturbed earth temp. Next, the process will calculate the zone heat pump equipment for the step zone thermal loads with the appropriate heat pump capacity type that adapts the BTU/hr capacity and Power (kW) for each step. Next, the process will calculate the kilowatt hours for each step, wherein in one embodiment for a cooling design can include: Step Kilowatt Hours=step zone btu/hr/step heat pump Btu/hr/(1−0.20*(1−step zone btu/hr/step heat pump btu/hr))*step heat pump kW*step operating hours. The process will then proceed to calculate the BTUs transferred to and from the ground for each step, wherein in one embodiment for a cooling design can include: Step Ground Btu Transfer=(−step heat pump Btu/hr−(step heat pump kW*3412))*(step zone btu/hr/step heat pump Btu/hr*step operating hours). Finally, the process will iterate all the steps and summarize the kilowatt hours and ground BTUs transferred to and from the ground and multiply the total kilowatt hours by the electric utility rate for the zone operating cost, wherein this data is sent to the simulation module/portal or simulation step 2240.

FIG. 9 illustrates one example scenario and output/simulation for calculated and simulated cooling operating costs for one zone and FIG. 9A for heating, both incorporating the operating hours scheduled within each discreet temperature increment for the building in a given year. More specifically, FIGS. 9 and 9A illustrate one scenario with sample data for one location with its corresponding climate data and having pre-defined building operating hours, building type, design temperatures and flow rate, borehole/pipe data, ground conditions, heat pump data, and thermal heating/cooling loads, among others. Further, this scenario illustrates simulated data for a non-hybrid cooling mode GHP design simulation. More specifically, the output includes the total operating zone operating cost and BTUs transferred to the ground for one year based on the received user inputted GHP design and calculated values with respect to FIGS. 1-8 and 20 and previously described processes within the disclosure described herein.

FIG. 10, illustrates one example scenario for calculated and simulated output for cooling operating costs for one zone for a GHP benchmark having no hybrid design, incorporating the hourly operating schedule within each discreet temperature increment for the building in a given year, wherein the GHP benchmark output data of FIG. 10 can be compared to the GHP design output of FIG. 9. Here, in one embodiment, the GHP benchmark output can be simulated using a different entering water temperature with respect to the GHP design entering water temperature. When comparing the output of FIG. 9 with FIG. 10, the GHP design total zone operating cost does not fluctuate much with respect to the GHP benchmark total zone operating cost, even though the entering water temperature for the GHP design is higher than the entering water temperature for the GHP benchmark. This illustrates that the GHP design simulation has about the same or substantially the same efficiency than the GHP benchmark having lower entering water temperature but with significant change in excess borehole pipe length for the GHP benchmark, further illustrating that a variation in enter water temperature does not have much of an effect on the GHP efficiency and in fact the GHP design will require much less borehole/piping length than the GHP benchmark (see FIG. 18), thus reducing the overall cost of the GHP design with respect to the GHP benchmark.

FIG. 11 illustrates one example scenario for calculated and simulated cooling operating costs for one zone for GHP design having a 20% hybrid design, incorporating the hourly building operating schedule data for each discreet temperature increment for the building in a given year. In particular, the output of FIG. 11 differs from that of FIG. 9, in that a percentage of the GHP design is hybrid. In this example, up to 20% of the load for the GHP system is transferred to a cooling tower. For example, once a pre-defined or pre-set threshold is met, such as temperature, zone BTU/hr, or enter water temperature, the GHP design can initiate the hybrid apparatus (in this case the cooling tower) to handle the excess load. In the example out of FIG. 11, the GHP design initiates the hybrid apparatus (cooling tower) when the ambient or outside temperature reaches 95 degrees Fahrenheit and the GHP design ground loop system has reached its maximum design load of 273,600 BTUs/hr for that zone, wherein the GHP heat pump system will continue to operate with the cooling tower handling the load over 273,600 BTUs/hr in each iteration step.

FIG. 12 further illustrates the process for calculating the total building's monthly operating rate and process the building's hourly operating schedule for each iteration step. More specifically, FIG. 12 follows a similar process and methodology as FIG. 9 for the zones, whereas FIG. 12 illustrates a process for calculating the total or entire building's monthly operate based on the calculated, simulated, and outputted GHP design and the total year building BTUs.

FIG. 13 illustrates one example scenario of output for a total building's calculated and simulated cooling total building energy requirements (BTUs) for a GHP design having no hybrid design, incorporating the hourly operating schedule data within each discreet temperature increment for the building in a given month and in a given year.

FIGS. 14, 15, and 16 illustrate detailed flow charts for processing and calculating the GHP design and benchmark of step 2200 for simulation and modeling. More specifically, FIGS. 14 and 15 are for a GHP design and FIG. 16 is for a GHP benchmark design. Referring now to FIG. 14, one embodiment for simulating at step 2240 additional parameters for the GHP design, such as borehole lengths and payouts, among others, can begin by applying and calculating the heat pump's outlet temperatures for a total system heat pump cooling and heating. Here, in one embodiment for a design with 100% water and no antifreeze the calculation can include: Geo Design Outlet Cooling=design entering water temp cooling−((((total building cooling btu/hr*−1)−(3.412*total heat pump kW))*1000)/(500*gpm cooling)); Geo Design Outlet Heating=design entering water temp heating−((((total building cooling btu/hr)−(3.412*total heat pump kW))*1000)/(500*gpm Heating)). Next, the process can include calculating a borehole length for the first year. In one embodiment for a cooling design the calculation can include: Cooling Load w/Compression=total cooling btu/hr+(3.412*total heat pump kW); Total Bore Resistance=borehole resistance+(cooling monthly operating rate*Rm ground resistance)+(Rd ground resistance*1.04); Total Heat Rate=((net ground annual heat rate*−1)+cooling load w/compression*total bore resistance))*1000; Net Temp Cooling=(design entering water temp+geo design outlet cooling)/2)−(undisturbed earth temp+0.1); Geo Design Borehole Length Cooling 1 yr=total heat rate/net temp cooling. Next, the process will calculate adjusting the ground conductivity and ground diffusivity for moisture content. In one embodiment, the calculation can include: Volumetric heat capacity Begin=(ground conductivity*24)/ground diffusivity; Soil Specific Heat=(ground moisture %*1.0)+((1.0−ground moisture %)*0.21); Soil Begin Density=volumetric heat capacity begin/soil specific heat; Soil Density=(ground moisture %*62.4)+soil begin density; Ground Conductivity Moist=(ground diffusivity/24)*(soil specific heat*soil density); Ground Diffusivity Moist=(ground conductivity*24)/(soil specific heat*soil density); Volumetric Heat Capacity Moist=(ground conductivity moist*24)/ground diffusivity moist. The process will then continue on FIG. 15.

Referring to FIG. 15, the process will continue from FIG. 14 by calculating the long term temperature ground effect. In one embodiment, this calculation can include: Net Ground Btu/hr Annual=(Total Ground Btu's Cooling+Total Ground Btu's Heating)/87601000; Borefield Layout Exposure=(grid across*2)+(grid down*2); Across Exposure=(grid down) (grid across+1); Down Exposure=(grid across)*(grid down+1); Percent Interference=1−(borefield layout exposure/(across exposure+down exposure)). Next, the process will calculate the long term thermal interference between adjacent boreholes (first step).

FIG. 16 illustrates a similar process flow methodology for calculating and simulating a GHP benchmark using benchmark parameters, such as benchmark entering water temperature. More specifically, the process can begin by applying and calculating outlet temperatures for heating and cooling for the total heat pump system. In one embodiment for a benchmark with 100% water and no anti-freeze, this calculation can include: Benchmark Outlet Cooling=Benchmark entering water temp cooling−((((total building cooling btu/hr*−1)−(3.412*total heat pump kW))*1000)/(500*gpm cooling)); Benchmark Outlet Heating=Benchmark entering water temp heating−((((total building cooling btu/hr)−(3.412*total heat pump kW))*1000)/(500*gpm Heating)). Next, the process can calculate ground annual heat rate, which can be based on the transfer of BTUs for a cooling and heating GHP system.

Next, the process will calculate the heating and cooling BTU/hr for each zone by taking into account the hybrid percentage (Geo Zone Btu/hr=total zone btu/hr*(1.0−hybrid percent)). Next, within building zone module 2160, the process will calculate the building operating hours schedule data in steps for each zone's thermal loads at each degree of outside ambient temperature for the received climate and site location data. Here, for each iteration step, the process is the same as discussed with respect to FIGS. 6, 7, 8, and results from the output of FIG. 11. Here, each iteration step comprises determining if a step zone load BTU/hr is greater than a Geo or GHP (ground loop) design zone load BTU/hr (Step Zone Btu/hr>Geo Zone Btu/hr) and if the false then the step zone load BTU/hr calculed will be used. If true, then Zone Btu/hr is set to equal Geo Zone Btu/hr and Hybrid Hours is set to equal step hours.

Still referring to FIG. 17, a hybrid cooling capacity and hybrid heating capacity are calculated. For hybrid cooling capacity, in one embodiment, this calculation can include: Cooling Tower Capacity=(total building cooling Load−total geo load)*1.25; or a Fluid Cooler Capacity=(total building cooling Load−total geo load); Cooling gpm=(hybrid cooling capacity*1000)/(500*(outlet temp−inlet Temp)); Design Wet Bulb Temp=from table 1; operating hours=summarize hybrid hours. For hybrid heating capacity, in one embodiment, this calculation can include: Hybrid Heating Capacity=(total building Heating load−total geo load); Water Flow Rate=heating gpm; operating hours=summarize hybrid hours. Once the hybrid data is calculated for each degree of ambient temperature according to the building operating schedule, then the data can be sent to the simulation module 2240 for simulating/modeling the GHP design with a hybrid system. As an example, FIG. 11 illustrates one scenario of output data for a GHP design with a hybrid system (20% hybrid). FIG. 19 also illustrates an simulation/model output and portal for GHP design with a hybrid system (25% hybrid).

More specifically, the iteration process can begin at step 300, wherein data from Table 13 can be used as an example. Here, the GHP application is attempting to solve for a variable x2, wherein the x2 can be GHP design entering or inlet water temperature (see FIG. 1, step 2100). Further, variable Array A and Array B can be obtained from a table, such as Table 13, wherein in this embodiment Array A can correspond to manufacturer provided heat pump entering water temperature (EWT) and array B can correspond to manufacturer provided heat pump capacity data for each EWT from array A. At step 302, the process will find the last key for variable A, and set the LASTKEY to equal END(A). At step 304, the process will then set a “Test” variable to equal to x2. At step 306, the process will then determine if x2 is greater than or equal to variable A[LASTKEY], and if false, then the process proceeds to step 408. However, if at step 306 the decision is true, then the process will set at step 410 for Test to equal to “A[LASTKEY]−1”. Referring back to step 408, if the decision is true, then the process will set at step 412 for Test to equal to “A[0]+1”.

Still referring to FIG. 20A, at step 414, the process will loop the variable Array A Value from start key to end key (start key=0; end key=3). At step 416, the process will then determine if the Value from step 414 subtracted from Test is greater than or equal to zero. If false, the process will at step 418 set LASTVALUE=B[KEY] and LASTKEY=A[KEY]. However if the decision at step 416 is true, then at step 420, the process will set y3=B[KEY], x3=A[KEY], y1=LASTVALUE, and x1=LASTKEY. Finally, at step 422, the process will solve, interpolate, or extrapolate the value for y2, wherein y2=y3−((x3−x2)/(x3−x1)*(y3−y1)). Hence, for the variable x2, the corresponding iterated y2. In this instance, x2 was the GHP design heat pump EWT (95 deg. F.) and y2 is the iterated, standardized, and calculated heat pump capacity (45.95 MBTU/hr).
